Educational testing device



Patented duly 12, 1932 PATENT OFFICE LAWRENCE mum, OI BERKELEY, CALIF OBNIA.

Application filed July 12,

This invention relates to-an educational testing device.

The principal object of this invention is to provide means whereby a pupil may an- 6 swer any number of questions after which the examination card may be quickly examined to determine the grade to be received by the student.

Another object is to produce a device of this character which is equally applicable to geographical questions as well as to other types of questions.

A further object is to provide means Whereby a stub may be retained by the school upon which stub will appear the students name, the date of-the examination and any other directions concerning the examiation, as well as the grade the student received.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like J parts throughout the same,

Figure I discloses a students examination card,

it is common practice in giving examinations togive a series of questions and a series of possible answers for these questions. The problem is for the-student to select the proper answer to. fit the question. It is a dificult matter to correct this type of examination and consequently it requires many hours of tedious work on the part or the teacher to grade the student. p

I have therefore devised examination cards having certain indicia thereon and certain characteristics to be later described which will immediately indicate whether the question has been properly answered or not.

In thev accompan drawin for the purpose of ustration'ls shown a Figure III is an enlarged detail fragmen- I wherein ED'C IGATIO NAL 'rns'rme nnvrcn 1929. Serial No. 377,868.

preferred embodiment of my invention, the numeral 5 designates the students card upon which is imprinted a plurality of horizontal lines 6 and vertical lines 7. These horizontal lines and vertical lines form boxes 8 in a: which circles 9 are printed. In the vertical columns are placed numerals to indicate the number of the answer while in the column 11 is placed the question number. Also imprinted on the surface of the card may be on maps as shown in detail at 12. Above this matter are certain indicia to indicate the course, .the students name, the date. of the examination and other special directions for the examination.

A space 13 is provided adjacent to one of tilt ,the margins of the card and adjacent to the perforated line 14. This perforated line forms the outer portion of the card into a. stub 16 also having a space 1-7 for the grade to marking. This stub also carries indicia indicating the course, name, date of examination and other directions.

The teachers card indicated as a whole by the numeral 18 is identical with the students to card with the exception that a portion 19 is printed a characteristic color, the reason for which will be later seen.

In using m cards, the student is given a list of questlons and possible answers and a punch. It is then necessary for the student to select the proper answer, and assuming that question 1 is asked, the proper answer is answer 5 and he will therefore punch out the card material in the first horizontal 135 column under the numeral 5 in the vertical column.

Supposing however that he selects the wrong answer, as for instance, answer 3 and punches out the card material in the vertical W column 3. The teacher, in preparing the master card, will punch with her punch the material in the horizontal column and vertical column 5, then inrading the students card, when the teacher s card is placed be- 95 hind the students card the colored surface of the teachers card will show through in the column 3 indicating a wrong answer. Had the student punched the correct answer the punch in his card would overlie the punch is correct for the questiongiven. 'As soon asthe teacher has determined thev grade the student is to receive, the grade is marked in the spaces 13 and 17, the stub 16 torn from the student card and filed for future reference. The student card is returned to the student, or a reverse procedure is followed, that is the student card may be retained and the stub given to the student. This is a matter of selection on the part of the teacher.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes relative to the shape, size, material and arrangement of arts may be resorted to without departing rom the spirit of the invention, or the scope of the sub oined claims.

Having thus described my invention, I claim 1. In an educational device, two cards havfining vertical columns, said sets crossing questions, the other sethaving indicia to designate respective ones of said other col-' umnsjto nd cate spacesfor respective answer indications where said columns cross each other, whereby one or more of several possible answers to respective questions may be indicated bypunchmgin one or more of said spaces, one of said cards being punched to indicate correct answers and becoming therebya-mastercard, the other, constituting a test card and adapted to be punched to indicate answers, whereby when said master card isplaced in registry over said test card any correct answer indications of said test card will register with the'answer indications of said master card, and when said master card, is'placed behind said test card, the master card will show through and thereby render conspicuous any incorrect answer indication of the test card and any failure toindicate answers will be visible on the face ofthe test card, the cards differing from each other in color whereby the master card can be more readily seen through. any incorrect indications in the test card.

In testimony whereof I aflix m signature.
